. NUT-LOCK.

Specification of Be it known that I, BURTON D. Lonc n, at

citizen of the United States, residing Magnolia, in the county of Kent and State of Delaware, have invented certain new and useful Improvements in Nut-Locks, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to nut locks, anll the principal object of'the same is to provide '9. simple device of the character stated that may be readily placed in locked or unlocked relation, and which will securely hold a nut in a locked position upon a bolt.

In carrying out the object of the invention generally stated above it will be understood, of course, that the essential features thereof are necessarily susceptible of changes in de tails and structural arrangements, one preferred and practical embodiment of which is shown in the accompanying drawings, wherein Figure 1 is a view in side elevation of the improved nut lock. Fig. 2 is a centr l longitudinal sectional view taken on the e 2-2, Fig. 1. Fig. 3 is a detail perspective view of the improved locking sleeve. Fig. 4 is a similar viewof the nut used in connection with this invention.

Referring to said drawings by numerals, l designates the bolt of the improved nut lock, the threaded portion 2 of which is provided with the spaced apart transversely arranged openings The nut 4 used in the present invention has the usual central threaded bore 5 and its outer surface is pro-\ vided with the ratchet teeth 6.

A sleeve 7 is provided with oppositely disposed longitudinally arranged side slats 8 and with an annular outstanding end flange 9, the end of which is provided with ratchet teeth 10 complemental to the ratchet teeth 6 of nut 4. 4

In assembling the improved nut lock, the nut 4 is screwed onto the threaded portion of bolt 1 and the sleeve 7 is titted over the bolt with its ratchet teeth 10 in engagement with the teeth 6 of nut 4:. A coiled spring 11 is then placed around sleeve 7 with one end bearing against the end flange Letters n Patented Aug. 23, 1910.

ment ring 12 loosely fitted around sleeve 7. Said spring 11 is then compressed and a locking pin or key 13 is passed through one ofthe openings-3 of the bolt 1 and through the slots 8 of sleeve 7, and forms a rest for ring 12 which is held in contact therewith by the pressure of spring 11.

It will be seen from the foregoing that the present invention provides means whererelat-ive rotation of the sleeve and bolt is prevented, and that the spring 11 is constantly exerting a pressure against the flanged end of said sleeve so that its toothed surface will be normally held in engagement with .the similar surface of nut i, thereby preventing rotation of said nut.

What I claim as my invention is l. A- device of the character described comprising a bolt provided with spaced trans se openings, a nut for said bolt having ratchet teeth on itstop surface, a sleeve provided with oppositely disposed side slots and a toothed end for engagement with the teeth of said n t, a. pin adapted to be passed through the s ots of said sleeve and selectively through one of the openings of said bolt, a ring movable on said sleeve, and a spring coiled about said sleeve and interposed between said ring and the toothed end of said sleeve.

2. A device of the character described comprising a bolt provided with spaced transverse openin s, a nut for said bolt having a toothed sur ace, a sleeve slidably titted over said bolt and havin an annular outstanding end flange provi ed with a toothed surface, said sleeve being'also provided with ippositely disposed longitudinal side slots, a pin adapted to be passed through said slots and one of the openings of said bolt, a ring loose" on said sleeve between said pin and the said end flange, and a spring coiled about said sleeve and having one end hearing against said rin and its other end hearing against said 61K fian e.

In testimony whereof hereunto aflix my signature in presence of two witnesses.
